Often, the root cause isn’t a dozen different sensors, but the one component that controls them all: the Engine Control Module (ECM).

With our pre-programmed module, you’re getting a part that is ready for installation right out of the box.

Common Signs of a Failing ECM

If your vehicle is exhibiting any of these symptoms, a faulty ECM could be the culprit. This is especially true if you see diagnostic trouble codes (DTCs) like P0601, P0606, or U0100.

• ✔ Check Engine Light is illuminated
• ✔ Engine stalling or misfiring
• ✔ Car won’t start or is very difficult to start
• ✔ Noticeable drop in fuel efficiency
• ✔ Poor engine performance or hesitation
• ✔ Transmission shifting problems
• ✔ Communication errors with diagnostic scan tools

A Straightforward Guide to Installation

Installing your pre-programmed 2007 G6 Engine Control Module is a manageable job for a confident DIYer. On the G6, the ECM is typically located in the left-hand (driver’s side) front of the engine compartment.

1. Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes for the system to fully discharge.
2. Locate the ECM: Find the module in the driver’s side front of the engine bay. It’s a silver metal box with several large electrical connectors.
3. Disconnect the Connectors: Carefully release the locking tabs on the electrical harnesses and pull them straight out from the ECM. Avoid pulling on the wires themselves.
4. Remove the Old Module: Unbolt the old ECM from its mounting bracket. Keep the hardware as you will need it for the new module.
5. Install the New Module: Mount your new, pre-programmed ECM onto the bracket and secure it with the original bolts.
6. Reconnect Everything: Plug the electrical connectors firmly back into the new module until they click into place. Reconnect the negative battery terminal.
7. Perform Security Relearn: You may need to perform a simple security relearn procedure. This typically involves turning the key to the ‘ON’ position for 10-15 minutes. Check your owner’s manual for the specific procedure for your vehicle.
